      My concern would be metal particles from the tapping operation getting into the cat. Possibly could take the exhaust pipe off and vacuum out the manifold. If the exhaust manifold is cast iron it is not easy to weld.

      @@johncooper4637 Just use ample amounts of grease on the drill bit and tap, as well as use a shop vac with a crevice tool near the working area. I would also use a steel plug. Biggest risk is breaking off the drill or tap, since the cast iron is severely work hardened. Time and patience. o7

May also be useful for return work that was declined for various reasons. Do you or, can you tag a vehicle to a video so, you may search/find video for that vehicle or similar that pass thru your shop? Local, State, Federal government would love to have this level of accountability for their acquisitions dept. to maintain their motor pools.

    I like this type of video, too, Ray. I don't need to see you spending 5-10 minutes to screw in an actuator, for example, or watch you remove a wheel. I usually fast forward through those parts, which works for me and those who like to see every one of a dozen bolts removed from a part. Watching you diagnose a problem is interesting. Oh, and my initial thoughts on that hole was to tap and plug. That's why the hole was drilled, to tap it and install a sensor. Simply tap it and install a plug.

    On a high mileage work vehicle like this, I wouldn't recommend risking braking the exhaust bolts and opening that can of worms. Not worth it to you or the owner, to replace the exhaust manifold. That hole looks symmetrical and an easy fix just capping it with a short bolt or plug. Welding it closed wouldn't be my first choice. More value for the owner addressing the steering box leak, damaged steering linkage and coolant leak..

    Drill and tap the hole and plug it.
    Has to be pipe threads because

      12:45 ok, you can not wire weld cast iron and many welders can't do it, however you might be able to stick weld with the right rod and technics, in other words you cannot weld cast iron and some types can't be welded at all.
      This would require a highly skilled welder to plug that hole correctly.
      Your better off drilling and taping it for a cast iron plug.
